I think when you are absolutely, without a doubt, a stereotypical color season, then it might work as a jumping off point. A lot of people, however, do not. I am one of those people.
According to this, I am a winter:

However, just look at the winters they are showing. How can warm Penelope Cruz and cool Elizabeth Taylor be the same? According to their results, everyone with very dark hair supposedly is a winter, which is utter rubbish. I do not have cool coloring at all.
So the only other thing I could be is an autumn, since summer and spring are clearly too light. However, the autumn color palette is hideous on me.
